// 2021-08-17: Calling io.AddFocusEvent() on ALLEGRO_EVENT_DISPLAY_SWITCH_OUT/ALLEGRO_EVENT_DISPLAY_SWITCH_IN events.
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
// 2021-05-19: Renderer: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
// 2021-02-18: Change blending equation to preserve alpha in output buffer.

// 2021-07-29: *BREAKING CHANGE*: Inputs: MousePos is correctly reported when the host platform window is hovered but not focused (using glfwSetCursorEnterCallback). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install the glfwSetCursorEnterCallback() callback and the forward to the backend via ImGui_ImplGlfw_CursorEnterCallback().
// 2021-08-17: *BREAKING CHANGE*: Now using glfwSetWindowFocusCallback() to calling io.AddFocusEvent(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() and forward it to the backend via ImGui_ImplGlfw_WindowFocusCallback().

// 2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
